don’t install application causally. I downloaded docker and deleted it before long, then restarted. Unexpectedly, my user folder(edwin) was eaten. I call help, my teacher tell my that I gave docker a power authority, so it will do something unexpected thing. Docker can only install in virtual environment or sever which don’t have important file.
Coincidentally, my windows was running a sever. Finally, I decided to reinstall my system. And I was reflecting the whole accident why it would happen. And the answer is back up system at regular intervals.
